Thanks, it also crashes when you click Options/Background Image as soon as you choose a .png file.

Never had the crash with .png file, so there's nothing I can do. Perhaps the file itself is non-standard?

The slot crash problem, while adding much-needed stability to MAME, was reverted by the powers that be.

At the moment, the whole slots-and-images thing is so wobbly, so likely to randomly crash at any time, that I'd recommend you stay with 0.187 for now.Unless some major fixes are done soon, or the whole thing backed out, there's unlikly to be a MESSUI 0.189 .
